Hi, Im wanting to change 2 things in my car: Gear Selector: Is it possible to change this to the S-Line ones? The one with bottom at the front and not side? OR to the NEW A6 selector? CHIPPING: can the Multitronic TDI be chipped? If so, anyone had it done? Would tou recommend getting it done? and if so, contact details of where to order from please. Thank you!
